HANDLE-BAR FOR BICYCLESL SPECIFICATION forming part of Letters Patent No. 624,657, dated May 9, 1899.

Application filed March 9, 1 8 97.

T0 ctZZ whom it 11mg concern:

Be it known that we, ERNEsT HENRY J oNEs and GEORGE WATERS TARVER, subjects of the Queen of England, residing at London, England, have invented certain new and useful Improvements in or Relating to Handle- Bars for Cycles and other Vehicles, (for which we have obtained Letters Patent in England, No. 19,624, dated September 4, 1.896,) of which the following is a specification.

This invention relates to handle-bars for cycles and other vehicles, its object being to render them readily adjustable while the machine is being ridden to bring the handles to a position convenient to the user and retain them securely therein under the stresses which come upon them in service.

According to this invention the handle-bar is made in two parts, one for each handle, each part being hinged at the inner endthat is to say, the end opposite to its handleto a head suited for retention in or at the upper end of the steering-tube of either new or existing cycles or the equivalent part of other vehicles. These inner ends of the halves of the handle-bar are geared together by an adjusting device in operative connection with both the halves of the handle-bar and provided either in the head or on the steeringtube, so that by its operation both the handles may be turned up or down about their pivots or hinges through equal angles to the extent desired. It is understood that the gearing is in all cases so arranged that both halves of the bar move simultaneously up or simultaneously down.

Figure 1 is a vertical central section, partly in elevation, of a head such as is hereinbefore referred to and the inner or hinge ends of the two halves of the handle-bar, together with worm adjusting-gear carried by the head. Fig. 2 is a transverse section on the line 2 2 of Fig. 1.

Like letters indicate like parts throughout the drawings.

In the above-described figures of drawings, Ais the head, which is tubular and T-shaped,

the stem A of the T being made of any form Serial No. 626,588. (No model.)

A. Each of these spherical portions is provided with a rack 0 D is a Vertical worm, to which is fixed a large milled head D. It turns in bearings in the axial line of the head A, so as to gear with the rack C on'each of the spherical parts 0 C and is retained in place by a plug A through which its lower end D passes and in which that end is retained by a nut D or other means capable of preventing endwise movement. If desired, packing-rings, such as E, can be inserted between the upper side of the plug A and the shoulder D on the spindle of .the worm D to adjust it endwise, as may be desired.

The worm D is preferably tapered,as shown, from one end to the other, the milled head being fixed upon the larger upper end. By

having it tapered it will take up, if lowered endwise, any wear between it and the racks 0 so as to prevent backlash and rattling.

It will be seen that by turning the tapered worm by means of the milled head D the porsimultaneously to the desired angle.

It is not essential that spherical parts 0 0 should be employed at the'hinge ends of the halves O C of the handle-bar, for any other convenient shape preferably fitting a correspondingly-shaped tube or socket of the head can be adopted.

We claim- A handle-bar for cycles comprising two parts or sections, a stem to which one end of each of said parts is pivotally connected, said pivotal-ends being provided with oppositelylocat'e'd rack or toothed portions, a tapered worm adapted for endwise or longitudinal tions 0 C of the handle-bar may be adjusted movement arranged between and engaging hands in thepresenceof the two subscribing with said toothed portions and adapted to witnesses.
